SL Mini Series Unidirectional Speed and Length Measurement

Scantron’s SL Mini Series non-contact, unidirectional speed and length gauges provide extremely accurate speed and length measurements in almost any sheet material or converting application.

The SL Mini Series has been used by clients in a range of industries and across production processes for web products, woven and non-woven materials, paper, plastic film, tapes, building materials, flooring and labelling. All can be accurately measured using the laser Doppler method employed by the SL Mini Series gauge.

Applications requiring a precise cut-to-length process benefit from the non-slip and highly accurate laser measurement technique which reduces scrap, increases uptime and improves material yield by eliminating product “Give Away” or “Short Length” claims.

SL mini Series gauges are money-saving, direct replacements for traditional problematic and high-maintenance contact wheel and roller-type devices and are extremely easy to install and operate.  Integration with production line controllers such as PLCs is eased by the availability of a wide variety of industry standard communications interfaces.

Scantron has a number of speed and length measurement solutions for a range of environments and applications. Contact us to discuss your requirements.
